WHAT IS SHARC?
SHARC is a database of musical timbre information by Gregory Sandell.
It stands for "Sandell Harmonic Archive." People for whom this dataset
may be useful are Acousticians, Psychoacousticians, researchers in
Music Percepion and Cognition, researchers in Digital Signal
Processing, Music Theorists, and Musicologists.
Over 1300 different notes have been analysed. Complete chromatic runs
from the standard playing range of essentially all the non-percussive
instruments of the modern orchestra have been included; for example,
individual analyses of 32 different oboe notes (the chromatic scale
from the pitches a#3 to f6) are available.
For each note, a short portion corresponding to the sustain or "steady
state" portion of the tone was selected and analysed with a Fourier
analysis. Each analysis consists of a list of amplitudes and phases
for all the note's harmonics in the range 0-10,000 Hz.
The source of the musical notes were the orchestral tones from the
McGill University Master Samples (MUMS) Compact Discs. These are
digital recordings of live musical performers.
MORE INFORMATION ON SHARC
The SHARC Timbre Database is described in detail in the documentation
accompaning the archive. You can get this file by:
1. Anonymous ftp to ftp.ep.susx.ac.uk; go to pub/sandell, and grab
README
2. World Wide Web, via the URL ftp://ftp.ep.susx.ac.uk/pub/sandell/README.html

HOW TO INSTALL SHARC
Here are instructions for installing the archive on a UNIX platform.
* Go to the directory where you want to install SHARC. You will need
about 9 free megabytes to perform the installation. Once
finished, the archive will occupy 4.5 megabytes space.
* ftp to ftp.ep.susx.ac.uk
* Enter user name "anonymous" and give your full email address as a
password
* Type "binary" to set the transfer to binary mode
* Type "get sharc.tar.Z"
* When the file is finished transferring (it is about 0.8 megabytes
large), leave ftp by typing "quit"
* Type "uncompress sharc.tar.Z". The result of this is that
sharc.tar.Z will be replaced by sharc.tar
* Type "tar xf sharc.tar". This will put the archive in a directory
called "sharc".
* Dispose of the sharc.tar file (type "rm sharc.tar") to reclaim
about 4.5 megabytes space.
